SLB-25.4-70PM 25.4 mm Dia. x 70.0 mm FL; Coated; Plano-Convex Lens 400-700nm
This is a Plano-Convex lens, type SLB-25.4-70PM, sourced from OptoSigma. The lens has a base shape of a circle and is designed for use within the wavelength range of 400-700nm. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens has a diameter of 25.4mm and a thickness at the edge of 1.9mm. The center thickness is 4.2mm, and the effective focal length (EFL) is 70mm. The front radius of curvature (R1) is 36.33mm, and the back focal length (BFL) is 67.2mm. The lens does not have an inner or outer radius.
The lens is coated with an opt m coating on both the front and back surfaces, enhancing its performance within its specified wavelength range. This lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
